Casey Anthony may have beaten a murder rap, but she is getting pounded in he court if public opinion.

Polls nationwide show that an overwhelming majority believe she killed her daughter, Caylee. Now lawmakers in several states -- including Florida, are considering laws that would make failing to report your child missing in a timely fashion a felony offense.

Aside: It's hard to believe it's not a felony already, isn't it?

Well, in Florida they are already calling it "Caylee's Law." The new measures were triggered, at least in part, by an online petition that had more than 700,000 signatures Friday.

"It's very sad that we even need a law like this, but Casey Anthony just proved that we do as unfortunate as that is,'' said Florida state Rep. Scott Plakon, who is sponsoring the proposal in his state.

Last week Casey Anthony was found not guilty of murder and guilty of giving false information to police. Her sentence amounted roughly to the time she has already served.

Florida's proposal would make it a felony for a parent or other caregiver to not report a child under the age of 12 missing after 48 hours. It also makes it a felony to not report a child's death or ""location of a child's corpse'' to police within two hours of the death.

Had Florida's measure been in place and Anthony been convicted, she could have faced another 15 years behind bars.

Other states are considering similar measures and the online petition at Change.org, started by an Oklahoma woman, calls for a federal law.
